Following are a number of back-translations of Revelation 9:2:

• Uma: “He/it opened the door to that sinkhole. When he/it opened it, much smoke rose/billowed out, like the smoke that rises from slashed-field that is burned-off. The sun and the atmosphere were dark covered/wrapped in the smoke from that sinkhole.” (Source: Uma Back Translation)
• Yakan: “When the hole was opened by that one called the star, immediately smoke came out from the hole like the smoke of a very big fire. Therefore the place/country became dark because the light of the sun was covered-over/hidden by the thickness of the smoke that came out from the hole.” (Source: Yakan Back Translation)
• Western Bukidnon Manobo: “He opened the pit whose depth has no end, and smoke came out like the smoke of a great forge. And the land became dark and the shining of the sun was blocked off because of the smoke from the pit.” (Source: Western Bukidnon Manobo Back Translation)
• Kankanaey: “When he had opened it, thick smoke immediately-came-out like that from a large burning. It blocked the sun, and the earth became-dark.” (Source: Kankanaey Back Translation)
• Tagbanwa: “Then that one referred to as the star opened that ravine. Smoke rose up like the thick smoke which comes from quite a few fields being burned. That’s why the sun and air became dark because of that smoke.” (Source: Tagbanwa Back Translation)
• Tenango Otomi: “Upon opening the cover of this hole, there came out smoke like the smoke of an oven. This smoke covered the light from the sun, laying over the earth.” (Source: Tenango Otomi Back Translation)
